Artist Jeanne-Claude, whose dramatic installations included wrapping fabric around the Reichstag in Berlin, has died at the age of 74.
The US artist, who worked alongside and under the name of her husband, Christo, died as a result of complications following a ruptured brain aneurysm.
A statement on the couple's website said he was "deeply saddened", but was committed to continuing their work.
"The art of Christo and Jeanne-Claude will continue," he wrote.
The couple - who met in Paris in 1958, and shared the same date of birth - had lived in New York for 45 years.
Recent work included 2005's The Gates, a highly-publicised installation which saw 23 miles of saffron drapes hung from a series of specially designed frames in New York's Central Park.
